Host:burley tobacco (Nicotiana tabacum (burley type)
L.)Descriptor: Adult(s)Description: Japanese beetles, occasionally feed on tobacco in groups, causing a skeletonization of the leaf. The beetles are less than 1/2-inch in length, shiny metallic green, with copper brown forewings. There are six tufts of white hairs on each side of the body near the outer margins of the wing covers. These adults usually emerge from the soil during late May. Their population peaks four to five weeks later. Feeding is the greatest on warm sunny days. A relative humidity below 60% retards flying and induces the insect to feed extensively. The larvae are white grubs that feed in the soil, devouring the roots of a large number of plants, especially turf grasses.Image type: Field Image location: United States
